What is an ET file, and what is the .et format?

An ET file is a spreadsheet workbook saved by WPS Spreadsheets. The .et extension is WPS’s native table format—similar in role to Excel’s .xlsx, but not the same file. Microsoft Excel has no built-in decoder for .et, so double-clicking in Excel often errors or garbles the sheet.

Why can’t Excel open an ET file?

Excel only understands its own spreadsheet families (XLS, XLSX, XLSM, CSV, and a few others). An ET file is a WPS workbook. There is no Excel add-in that “unlocks” .et. Open it in WPS Spreadsheets, then Save As .xlsx if the recipient must use Microsoft Excel.

What software can open ET files on Windows, Mac, and phone?

WPS Office (Spreadsheets) opens .et on Windows, Mac, and mobile. LibreOffice may open simple ET sheets with mixed results on charts and WPS-only functions. Random “ET viewers” and most web converters are weak on this format. WPS is the native app for a complete workbook.

Can I open an ET file by renaming .et to .xlsx?

No. Changing the letters after the dot does not convert the file. Excel still sees WPS’s internal structure and typically reports a corrupt or unreadable workbook. Convert by opening in WPS Spreadsheets and using Save As → Excel Workbook (.xlsx).

How do I convert an ET file to XLSX or XLS without losing formulas?

Open the .et in WPS Spreadsheets, check formulas, charts, and cell formats, then File → Save As → .xlsx (or .xls for older Excel). Stay on the desktop so the file is not uploaded. Recheck WPS-only functions after export—those may need a standard Excel equivalent.

Will conversion keep formulas, charts, and cell formats?

WPS → Save As XLSX is the path that preserves the most: number formats, column widths, standard formulas, and most charts. What web converters drop first are charts, merged headers, and WPS-specific functions. After export, open the XLSX in Excel once and scan: totals, print area, and any named ranges. If a WPS-only function blanked out, replace it with an Excel equivalent while you still have the original ET.

How to batch convert multiple ET files

Trade and ops teams often get a folder of domestic quotes as .et. In WPS you can open each workbook and Save As XLSX, or use the suite’s batch/export tools when you have many files with the same target format. That beats twenty uploads to a website that may not even parse ET. Keep originals until a sample XLSX opens in Excel with formulas intact. Do not mix renamed fakes into the same folder as real conversions.

How to open an ET file without WPS — is there an online converter?

Without WPS, options shrink: LibreOffice for a rough look, or a website if the sheet is public and simple. There is no high-quality Excel-native opener. “How to open et file without WPS” usually still ends in installing a spreadsheet app that understands ET—or asking the sender for XLSX. Online converters that advertise every extension often fail on ET or strip charts. If you must use one, strip personal columns first and expect a watermark or size cap on the free tier. For a priced quote, offline WPS is the safer default.

Will an online converter leak a quote?

Unknown hosts can store uploads. Customer prices and SKUs should stay on your PC. WPS Save As never needs that upload.

Opened garbled or “corrupt” in Excel?

Usually the wrong app or a renamed suffix. Reopen the original .et in WPS. If the ET itself is damaged, try WPS’s repair/open options and a backup copy from the sender.

Free convert watermarks and size caps

Website free tiers often stamp pages or reject large workbooks. WPS everyday open/edit/Save As does not put a converter watermark on your XLSX.

Password-protected ET

You still need the password. Open in WPS, unlock, then Save As XLSX. A converter site cannot bypass encryption—and you should not paste the password into a random form.

Why cannot Excel open an ET file?

Microsoft Excel has no built-in ET decoder. If you File → Open a .et workbook, Excel typically errors, shows garbage, or treats the file as corrupt. Formulas and WPS-only functions do not “translate themselves” inside Excel.

That is the Microsoft-ecosystem gap: great for XLSX, silent on ET. Searching “open et file in excel” does not unlock a hidden Excel button. The reliable path is open in WPS, then export a real Excel file.

If Excel already “opened” something after you renamed the suffix, treat that sheet as untrusted until you reopen the original .et in WPS Spreadsheets. Garbled headers and #REF! rows are common after a fake extension change.

Can I just rename .et to .xlsx to open it?

This is the most common beginner trap. Changing quote.et to quote.xlsx only changes the label. The bytes inside are still a WPS workbook. Excel then reports a corrupt file—the search phrase “et file corrupted when open in excel” is often this rename, not a damaged disk.

Do not rename ET to XLSX without converting

Real conversion is Save As (or export) from an app that can read ET. Keep a copy of the original .et until the new XLSX opens cleanly in Excel.
